DOOR FOR RAILWAY-CARS.

SPECIFICATION forming part of Letters Patent No. 788,646, dated May 2, 1905.

Original application filed February 2,1903, Serial No. 141,415. Divided and this application filed November 21,1903. Serial No. 182,064.

To (LI/Z whom it may concern:

Be it known that we, FRANK S. INeoLDsBY and Jos EPH R. BOWLING, citizens of the United States, residing at St. Louis, in the State of Missouri, have invented a certain new and useful Improvement in Doors forRailway-Oars, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings.

The invention relates to certain improvements in doors for railway-cars, particularly such as are constructed of metal, the features which are peculiar to the invention being clearly described herein and being definitely set out in their essential combinations in the claims, to which reference is hereby made for a summary of the invention.

In the drawings, Figure 1 is a side elevation of a portion of the outside of a car, showing how our doors are applied thereto. Fig. 2 is a longitudinal sectional View of a portion of a car, showing our doors as they appear when viewed from the inside of the car. Fig. 3 is a transverse section of so much of the car as is necessary to show our doors applied thereto. Fig. 4C is a detail in side elevation at one of the lower corners of the upper side door, showing the gravity-latch. Fig. 5 is a vertical cross-section of Fig. 4. Fig. 6 is a side elevation of the latch itself, being taken from the same point of view as Fig. 4:, omitting intermediate members.

The side of the car is designated A. The side is composed generally of two portions-a lower plate a, terminating in an angle-strip a, and an upper portion composed of slats a". At the upper edge of the slatted portion is a chord consisting of a pair of oppositely-facing anglebeams a a riveted back to back through their vertical sides. At the bottom of the side is a lower chord, itself a plate-girder, composed of the plate a and upper and lower flanges a a therefor. The plate a of this girder stands outside of and continues downward from the plate a.

. JD design ates a cross-beam riveted at its ends to the plate-girder and braced by strengthening angle-irons d.

F designates the ridge-plate of the car, made in two sections resting on and secured to the crossbeam D. The construction and support of the ridge-plate are shown, described, and I claimed partly in our prior application, Serial No. 120,922, filed August 25, 1902, and partly in the application of Frank S. Ingoldsby, Serial No. 120,959, liled August 25, 1902.

Pivoted to the ridge-plate are dumpingdoors, as G, provided with floor-beams g, which are adapted to be engaged by hooks K, pivoted to the sides of the car and projecting through the lower flange a thereof, these hooks being connected by a link L for operating the same.

The car is provided at each end with an inclined floor O, as shown in Fig. 3. In the side of the car is provided a doorway, across the upper portion of which extends a plate a.

The structure of the car-body proper, including the sides, dum ping-doors, and inclined floor, does not form any part of the invention covered by this application, the same being embraced in application, Serial No. 141,415, filed February 2, 1903, of which this is a division.

The doorway through the car side is adapted to have its lower portion closed by the door T, which is hinged at the lower edge of the doorway. Thisdoormaythusbeturneddown into a horizontal position, as shown in full lines in Fig. 3, forming a platform upon which the load may be wheeled by a wheelbarrow in filling the car, or it may be turned up vertically to close the doorway, as shown in dotted lines in that figure. On the under side of this door it is provided with steps t to enable the attendant to more easily climb out of the car.

The upper portion of the doorway above the door T and below the platen of the car side is adapted to be closed by a small sliding door U, which carries at its upper end rollers a, whereby the door may he slid along and suspended from a track a, carried by the outer side of the car side. When in position, the lower edge of this door is swung into the doorway, thus not only closing the doorway, but holding itself from longitudinal shifting. This is shown, described, and claimed in our application, Serial No. 120,923, filed August 25, 1902.

In order to provide a simple and efiicient latch for locking the two doors which close the doorway in place, we have provided the mechanism shown more clearly in Figs. 4c, 5, and 6. Pivoted to a stud a), secured to the transverse flange a of each of the vertical posts a at the doorway, is a gravity-latch V, so proportioned that it it be turned up into the position shown in dotted lines in Fig. 5 gravity will tend to hold it, whereas it may be swung downward by a slight force into the position shown in full lines in that figure. When the latch V is turned up into the position shown in dotted lines, it is out of the way of the door T. IVhen the latter has been turned up into vertical position, however, and the latch swung downward into its lowermost position, its nose o passes into an opening a in the flange a and, standing in front of the door T, eflectively prevents it from being turned down. Now when the small upper door U is swung inward its lower end it lies across a projecting boss '0 on the side of the latch V, so that the door U locks this latch in its downturned position, thereby effectively locking the door T. The door U carries a pair of sliding bolts 10', connected by a link a to an operating-handle u When this operating-handle is drawn outward, the bolts are drawn toward each other, and when the operating-handle is forced inward the bolts are spread outward. In this outward spreading the bolts pass between the outer flange of the post a and the edge of the latch V, and thus hold the upper door in place against either inward or outward movement. A sealpin it through the operating-handle a and a stationary clip holds the bolts in place. It will thus be seen that an effective lock is provided. The lower doors are locked by the latches V. The latches are locked by the upper door U. The upper door is locked by the bolts it, and these bolts are locked by the seal-pin. The gravity-latch V is so proportioned that when it is turned into the uppermost position gravity will normally hold it there; but a slight jerk to the car will throw it downward. Thus if the attendant turns down simply one latch after he has turned up the door T the probability is that the other will be automatically thrown down in some movement given to the car before the upper door is locked in place.

Having described our invention, we claim 1. In a car, the combination of a side provided with a doorway, a door hinged to the lower portion of said doorway and adapted to be swung into a substantially vertical or closed position, a door-post having a face at right angles to said side and provided with an opening, and a gravity-latch pivoted to said face above the upper edge of said door to swing at right angles to said face and so positioned as to be swung down to engage the edge portion of the door when the latter is closed, said latch being provided with a nose adapted to take into the opening in the post.
